DNA Fingerprinting – Using Restriction Enzymes Kit [1829]

The DNA Fingerprinting – Using Restriction Enzymes Kit offers an in‑depth, hands‑on introduction to restriction enzyme digestion within the exciting context of forensic science. In this investigative laboratory activity, students act as forensic scientists by cutting DNA with restriction enzymes and comparing the resulting banding patterns to identify the source of a crime scene sample.

Students digest plasmid DNA using Eco RI and Hind III restriction enzymes, then separate the DNA fragments using agarose gel electrophoresis. By comparing the DNA fingerprint from the crime scene to those of two suspects, learners develop a clear understanding of how genetic analysis is used in real‑world criminal investigations. The practical focus encourages problem‑solving, analytical thinking, and discussion.

Designed for 8 student working groups of 2-4, this comprehensive kit includes high‑quality reagents and stains to ensure clear, reliable results. It provides an excellent opportunity for students to build confidence with advanced molecular biology techniques while reinforcing key theoretical concepts.
